I am receiving the error below

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

git switch -c

Or undo this operation with:

git switch -

Turn off this advice by setting config variable advice.detachedHead to false

    Hi @hectorrguerrero ,

    Thanks for sharing the error details, this is really helpful.

    I’m going to check in with the course authors to make sure we’re giving you the most accurate guidance for this setup. I’ll follow up once I hear back from them.

    In the meantime, if you can share a bit more about your environment (OS, setup, etc.), that may help us narrow things down.

    Hi @hectorrguerrero ,

    Your file list looks normal.

    If you think some files are missing, it might be because submodules were not downloaded. The free5gc repository uses submodules.

    Try cloning with:
    git clone --recursive -b v4.2.1 -j `nproc` https://github.com/free5gc/free5gc.git

    I encountered more issues witth the course and, I need to move forward., are you still supporting the material and the lab. I havent heard from anyone in 2 days. The issues I am having are related to the GO version you are using not being compatible with the free5gc code.

    could you please reach out to me as soon as spossible.

    Regards,
    Hector Guerrero

    Hi @hectorrguerrero,

    It looks like you’re not blocked on our end, but the forum may be preventing the post due to how the content is being added.

    If you’re pasting logs or code directly into the post, it can sometimes trigger a security filter. You might try using the code block option in the editor (from the toolbar) instead, or attaching the logs as a file.

    Let me know if that works for you.

    Hi @hectorrguerrero,

    Perhaps you can create the GH issue on https://github.com/free5gc/free5gc/issues for pasting the error log, then we'll try to solve your problem on that thread.
